Measurement range: 10-500 m/11-550 yd./33-999 ft. In addition to actual distance, horizontal distance, height, angle and vertical separation (difference in height between two targets) measurement functions, three-point measurement (height between two points) is available The results are displayed on both internal and external LCD panels. The external panel displays all results simultaneously. Target Priority Switch System for measuring overlapping subjects: First Target Priority mode displays the distance of the closest subject — useful when measuring the distance to a subject in front of an overlapping background. Distant Target Priority mode displays that of the farthest subject — useful in wooded areas. High-quality 6x monocular with multilayer coating produces bright, clear images Long eye relief design affords eyeglass wearers easy viewing Dioptre adjustment function Single or continuous measurement (up to 20 seconds) Waterproof (up to 1 meter for 10 minutes) but not for underwater usage; the battery chamber is water resistant Wide temperature tolerance: -10°C to +50°C Internal display 1.Actual (linear) Distance 2.Horizontal Distance 3.Height 4.Height between two points 5.Three-point measurement 6.Unit of measure (m/yd.)

Points 2 and 3 can be reversed. Measurement example (two-point height measurement) When the measurement is successful, you see the height from the base to the top displayed on the internal LCD with Hgt+Hgt2 (solid). For more information, refer to the external LCD. "Base" and "Top" can be switched.
